Question

A circular gift has a 4.75 inch radius. Ilyssa wants to wrap a ribbon that costs $0.50 per inch around the gift. How much money will she spend?

Answer 1

Answer:

$14.93

Step-by-step explanation:

If the cost is per inch, then we need perimeter otherwise if the cost was per square inch we would have looked for the area.

Total cost=circumference* cost per inch

Circumference of a circle is given by

$C=2\pi r$

Where r is radius. Substituting 4.75 inch for r then

$C=2\pi\times 4.75=29.857142857142\\C\approx 29.86 inch$

Cost=29.86*0.50=$14.93
